Research Abstract

We reported that early lymphopoiesis is suspended during pregnant period and high-estrogen condition. By means of intensive analyses on the influence of estrogen on the hematopoietic microenvironment, we have found that soluble Frizzled-related protein 1(SFRP1) acts as a mediator of estrogen action. In the present study, we have constructed transgenic mouse models of SFRP1 or other SFRP-related molecules to evaluate their biological significance in vivo. We have observed severe leukocytopenia, particularly decrease of B-lymphocytes, in SFRP over-expressing mice.
